Abstract

The invention concerns naphtholactam derivatives of formula (I), in which: R.sup.1 represents hydrogen, optionally substituted C.sub.1 -C.sub.6 alkyl C.sub.5 -C.sub.6 cycloalkcyl or substituted phenyl; R.sup.2 and R.sup.3 represent hydrogen, C.sub.1 -C.sub.8 alkanoyl, optionally substituted benzoyl, optionally substituted C.sub.2 -C.sub.4 alkyl, optionally substituted C.sub.2 -C.sub.4 alkenyl, optionally substituted C.sub.2 -C.sub.4 alkinyl, a halogen, nitro, sulphamoyl, optionally substituted hydroxy, optionally substituted mercapto, C.sub.1 -C.sub.6 alkysulphonyl or optionally substituted phenylsulphonyl; R.sup.4 represents hydrogen or, with R.sup.3, a group of formula (II); R.sup.5 represents hydrogen or C.sub.1 -C.sub.6 alkyl; R.sup.6 represents cyano, carbamoyl, C.sub.1 -C.sub.4 mono- or dialkylcarbamoyl carboxyl or C.sub.1 -C.sub.4 alkoxycarbonyl; and R.sup.7 represents substituted C.sub.1 -C.sub.4 alkyl, optionally substituted C.sub.5 -C.sub.13 alkyl or benzoyl. Also disclosed is the use of these derivatives for dyeing or printing textiles.

R.sup.2 and R.sup.3 are independently of each other hydrogen, C.sub.1 -C.sub.8 -alkanoyl, substituted or unsubstituted benzoyl, substituted or unsubstituted C.sub.2 -C.sub.4 -alkyl, substituted or unsubstituted C.sub.2 -C.sub.4 -alkenyl, substituted or unsubstituted C.sub.2 -C.sub.4 -alkynyl, nitro, sulfamoyl, hydroxyl, mercapto, C.sub.1 -C.sub.6 -alkoxy, substituted or unsubstituted phenoxy, C.sub.1 -C.sub.6 -alkylthio, substituted or unsubstituted phenylthio, C.sub.1 -C.sub.6 -alkylsulfonyl or substituted or unsubstituted phenylsulfonyl, with the proviso that one of R.sup.2 and R.sup.3 is other than hydrogen,
R.sup.4 is hydrogen or together with R.sup.3 a radical of the formula ##STR16## R.sup.5 is hydrogen, R.sup.6 is cyano, carbamoyl, mono- or di(C.sub.1 -C.sub.4 -alkyl)carbamoyl, carboxyl or C.sub.1 -C.sub.4 -alkoxycarbonyl, and
R.sup.7 is substituted or unsubstituted C.sub.5 -C.sub.13 -alkyl with or without interruption by from 1 to 3 oxygen atoms in ether function, by from 1 to 3 sulfur atoms or by from 1 to 3 imino or C.sub.1 -C.sub.4 -alkylimino groups, or is benzoyl.
